AIM: To investigate the presence of total gut viral content in obese mice, and establish correlation with obesity associated metabolic measures and gut microbiome.METHODS: Fresh fecal samples were collected from normal and obese(Leptin deficient Lep^(ob/ob)) mice. Total viral DNA and RNA was isolated and quantified for establishing the correlation with metabolic measures and composition of gut bacterial communities.RESULTS: In this report, we found that obese mice feces have higher viral contents in terms of total viral DNA and RNA(P 0.6), whilst negatively correlated with bacteroidetes and bifidobacteria. CONCLUSION: This study suggests the strong correlation of increased viral population into the gut of obese mice and opens new avenues to explore the role of gut virome in pathophysiology of obesity.

Objective:To explore risk factors for the development of pneumothorax in patients with COVID-19 during the second COVID-19 wave at a northern Indian level 2 health facility.Methods:Patients suffering from SARS-CoV-2 infection during the second wave of the COVID-19 pandemic in India(January-June 2021)at a tertiary care teaching hospital and level 2 COVID care facility were included.Cases who suffered from SARS-CoV-2 infection but did not develop pneumothorax were selected as matched controls.All details regarding demographics,clinical presentation,treatment,and outcome were recorded in a semi-structured proforma.Results:Eleven patients with COVID-19 developed pneumothorax during the study period and 40 controls were included in the study.Five cases were smokers in comparison to only two in the control group.Type 2 diabetes mellitus was the most common comorbidity among both groups.Median change in C-reactive protein overall for cases and controls were around+14.0 and-41.9 and was statistically significant.Conclusions:Inflammatory markers like C-reactive protein have significant correlations with the development of pneumothorax in COVID-19-infected patients.There is no sex predisposition to develop pneumothorax among patients with COVID-19.

Aim European and North american studies have suggested that nitrogen(N)depositions reduce plant diversity and increase primary pro-ductivity due to changes in plant traits.To predict the vegetation response to future global change,experimental validations from other regions are widely needed.We assessed the effects of N treat-ment by urea fertilization on the diversity and biomass of the her-baceous plant traits(HPTs)in a dry tropical environment of India.Methods Diversity and biomass of different HPTs were determined on the basis of data collected in year 2010,from 135,1 m×1 m plots dis-tributed over 15 locations.The plots were treated with urea fertilizer in different doses(Control,60 kgNha−1 yr−1 and 120 kg N ha−1yr−1)since 1st January 2007.The plots were ordinated and data were subjected to appropriate statistical analyses.Important Findings Correspondence analysis(Ca)suggested uniqueness of species composition due to N amendment.species number and biomass of the trait categories varied due to N fertilization and traits.all studied trait categories(except N-fixers)yielded maximum mean species number at moderate level of N fertilization.Different levels of N fer-tilization exhibited different species diversity-primary productivity(D-P)relationships.Further,study showed reduction in plant diver-sity due to increase in biomass at high rates of N addition.Conclusions Tall,erect,non N-fixers,annuals,grasses HPTs were favoured by N enrichment.N dose above 60 kg enhanced the biomass of fast grow-ing,erect,annuals,non N-fixers,nitrophilic HPTs.The changes in traits with N addition,especially the increase in annuals and grasses and decrease in typically N-rich N-fixers,have implications for sus-tainable cattle production.
